[Adducts cords.] Crico-arytenoideus posticus: depression near ridge on posterior surface of cricoid cartilage(F)—projection at external angle of base of arytenoid cartilage(F) (Recurrent laryngeal). [Abducts cords.] ^ Arytenoideus : single muscle in the median line, fills up posterior concave surface of arytenoid cartilages. Superficial fibres pass from apex of one cartilage to base of other. Deep fibres pass between posterior surfaces of the cartilages (Re- current laryngeal). [Approximates cords.] ANTERIOR VERTEBRAL REGION. Eectus capitis anticus major: four tendinous slips from anterior tubercles of transverse processes of 6th, 5th, 4th, 3rd cervical vertebrse(T)—basilar process of occipital(F) (ist, 2nd, 3rd and 4th cervical). [Flexes head and cervical spine.] Rectus capitis anticuu minor: root of transverse process and lateral mass of atlas(F)—basilar process of occipital(F) (ist cervical). [Flexes head.] Rectus lateralis : superior surface of transverse process of atlas(F)—jugular process of occipital(F) (ist cervical). [Flexes head to same side.] Highest ijitertransverse muscle. Longus colli: Superior oblique part. Anterior tubercles of transverse processes of 3rd, 4th, 5th cervical vertebrse(T)— tubercle on anterior arch of atlas(T). Inferior oblique part. Bodies of first three dorsal(f)—anterior tubercles of trans- verse processes of 5th and 6th cervical(T). Vertical part. Bodies of lower two cervical and upper three dorsal and tranverse processes of 4th, 5th, 6th, 7th cervical vertebrse(FT) —bodies of 2nd, 3rd and 4th cervical vertebrae(T) (Cervical nerves). [Flexes cervical spine.] LATERAL VERTEBRAL REGION. Scalenus anticus : anterior tubercles of transverse pro- 'cesses of 3rd, 4th, 5th, 6th cervical vertebras(T)—scalene tubercle on inner border and superior surface of ist rib(T)— (Branches of lower cervical). [a raises ribs as in forced inspira- tion, B ilexes spine and bends neck to same side.] Phrenic nerve lies along anterior surface; subclavian artery passes behind at origin. Scalenus medius : posterior tubercles of transverse pro- cesses of lower six cervical vertebr3e(T)—rough elevation on](https://iiif.wellcomecollection.org/image/b21222927_0035.jp2/full/800%2C/0/default.jpg)
